What Is Hot and Sour Soup?

Chinese and American Chinese soup · Chinese name · Ordering guide

Hot and sour soup is less about chile heat than about the balance of acidity and peppery warmth. A strong version should make the sour and spicy contrast immediately clear without turning muddy or heavy.

Quick answer

Hot and sour soup is a peppery, tangy soup usually built from vinegar, white pepper, broth, tofu, egg, mushrooms, bamboo shoots, and sometimes pork. The benchmark is balance: the hot and the sour should register right away, and the thickened texture should stay smooth rather than gluey.

What it tastes like

It should be sour, peppery, savory, and thickened, often with a mix of soft tofu, egg ribbons, and crunchy vegetables. Good restaurant versions feel silky rather than pasty, which is one reason chefs are careful about when the starch goes in.

How it appears on menus

It appears in soup sections, lunch specials, and takeout menus. The restaurant style determines whether it is delicate, thick, mild, or aggressively seasoned.

Common variations

  • American Chinese hot and sour soup
